Step 1 — Computer Connection
The MLC 206 must be connected to a PC in order to configure the controller. The
configuration port, shown in the rear panel view below, is used for system control
and for loading configuration and driver files into the MLC.
1. Connect a host computer to the MLC 206 Config port via the rear
panel 9‑pin HD female RS‑232 connector. Use a serial cable with
9‑pin D connectors.

with the software. Connections for IR and serial control can be installed
after configuration.

3. To power the MLC, connect a 12 VDC power supply or an optional
MediaLink Switcher (MLS) to the MLS/Power port, and connect the power
supply or the switcher to a power source.

Step 2 — Software Installation
The MLC must be configured before it can send commands to the projector or other
devices. Install the MediaLink Control Program software on the host PC. To install
the software, run SETUP.EXE from the Extron‑provided disk. Follow the instructions
that appear on the screen.
N The software is also available at www.extron.com.

Step 3 — Setting up projector control
Device drivers allow the MLC 206 to control projectors and other source devices via
RS‑232 or IR.
N It is strongly recommended that an RS-232 control (filenameRS1.mll) file for
controlling a projector be used whenever possible.
To load a driver and configure the MLC 206:
1. Start the MediaLink Control Program.
The appearance of the screens varies depending on which
accessories (control modules and/or MediaLink Switcher)
are connected to the MLC, as shown in the following
pictures.

IRCM-DV+, and RCM-SC connected
2. Load a projector driver: select the third tab, Controller (MLC) Config, and
select the Load Extron Driver button, as shown in the following illustration.
Choose the appropriate projector driver (filename.mll) from the on‑screen
menu. If the projector brand and model are not listed, check the Extron Web
site to see if a new driver is available or enter user‑defined RS‑232 strings. See
“Advanced Projector Config” in chapter 4 of the User’s Manual for details.

5
3. Configure the buttons. Use the
drop‑down box associated with each
button to select the command to be
issued or function to perform, as
shown at right.
Each configured button has a green or red dot on it.
N If a button has been previously configured, it will have a red (IR) or
green (RS-232) dot to indicate that an IR or RS-232 code has been associated
with it.
4. Choose a volume control option. Select Projector if
planning to use the projector display speakers or if using
the projector display as a preamp. Select Switcher (MLS)
when using an external switcher as an audio preamp or
amplifier.
Step 4 — IR learning
If there are no drivers available, the MLC can learn IR commands to control
projectors or other devices. IR learning is required to configure control modules to
control devices such as DVD players.
1. Select the third tab, Controller (MLC) Config.
2. Click on the appropriate button on the control module or the MLC to learn IR
codes.
N If a button has been previously configured, it will have a red (IR) or
green (RS-232) dot to indicate that an IR or RS-232 code has been associated
with it.

4. Click on OK to begin the learning process.
During IR learning hold the device remote control 4 inches to 14 inches
(10 cm to 36 cm) away from and directly in front of the MLC’s IR pickup
device.

Step 5 — Completing the installation
1. Save the configuration by selecting Save CONFIGURATION as..., and name it
appropriately.
2. Connect the MLC 206 to the projector for RS‑232 projector control.
a. Disconnect the power from the MLC (and the optional MediaLink Switcher,
if applicable) and from the projector.
b. Plug the 9‑pin D connector of the RS‑232 projector control cable (such as an
Extron UC 50’ cable) into the projector RS‑232 port. A cable adapter may be
required.
c. Connect the other end of the projector control cable to the MLC
Display/Source Control RS‑232 port. Wiring depends on the projector. See
the diagrams below and on page 8, and the pin assignments in the projector
user manual. Also see the display driver setup document available from
the download page of the Extron Web site.
N In most cases only the transmit (Tx), receive (Rx) and ground connections will
be needed. Wiring varies depending on the projector model.

3. Install the IR Emitter(s) in the IR port as shown in the following illustration,
and attach the head of each IR Emitter to an IR‑controlled device (VCR,
DVD player, projector).
N Place the IR emitter directly over the IR pickup device of the equipment.

to the MLC 206. Refer to chapter two of the MLC 206 User’s Manual and to the
accessory manual(s) for wiring diagrams and installation details.
5. Reconnect the power supply or optional MediaLink Switcher (MLS) to the
MLS/Power port and connect power to all controlled devices.
6. Verify the system operates correctly when selections and adjustments are made
at the front panel and/or from the User Mode section of the control software.
Adjust cabling or retry IR learning as needed.
7. Disconnect the host PC from the MLC 206, remove power from the MLC
(unplug the power supply or switcher), and label the inputs (see the
MLC 206 User’s Manual for details).
8. Mount the MLC and accessories into the wall or furniture, and restore power.
